SH115B Insulation Oil Dielectric Loss and Resistance Tester
SH115B insulation oil dielectric loss and resistivity tester is an integrated high-precision instrument used for testing the dielectric loss angle and volume resistivity of liquid insulation media such as insulation oil. Internally integrated with main components such as dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss testing bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source, etc. The heating part adopts the currently advanced high-frequency induction heating method, which has the advantages of non-contact between the oil cup and the heating element, uniform heating, fast speed, and convenient control. The AC test power supply adopts AC-DC-AC conversion method, effectively avoiding the influence of mains voltage and frequency fluctuations on the accuracy of dielectric loss testing. Even if the generator generates electricity, the instrument can operate correctly. The internal standard capacitor is an SF6 gas filled three pole capacitor, whose dielectric loss and capacitance are not affected by environmental temperature, humidity, etc., ensuring consistent accuracy even after long-term use of the instrument. The measurement of resistivity complies with GB/T5654.
The instrument adopts fully digital technology internally, with intelligent automated measurement and multiple measurement modes. It is equipped with a large screen (320 × 240) touch sensitive display, a fully Chinese menu, and Chinese prompts for each step. The test results can be printed and output, and operators can proficiently use them without professional training.
